2)    Is it just me, or is the distance between the trim tab servo output
arm and the trim tab actuator going to come out so small that you can't fit
two of those clevises (clevi?) between the two?

Gary,
You can cut off the clevi (who knows?) a small amount to shorten the
assembled length. If you don't allow for a nut between them (looks better),
be sure to use a depth gauge to ensure the connecting rod is equally
threaded into each clevis at least 3/8." If you don't engage enough threads
on each one, it will fail. Just examined one yesterday where the rod had
broken out of the clevis. It appeared to have only about 3/16" of threads
engaged, and had apparently flown that way for several years before giving
up the ghost.

Be sure your trim tab can move through the entire range of the trim servo,
and that it's within your required limits at both ends of travel. Sooner or
later, the trim system will give trouble; one failure mode is the trim motor
driving to a limit. I'd therefore recommend you check to see how difficult
it is to fly/control the aircraft with each trim at both limits during your
test phase. You might be surprised, especially on the pitch trim.

Hope this helps!
